Abstract
The utility model provides a welded type steel pipe fitting, which is characterized by comprising a main pipe fitting 1 and a white steel pipe 2, wherein the white steel pipe 2 is welded on the end part of the main pipe fitting 1, and the inner surface or the inner surface and the outer surface of the main pipe fitting 1 and a welded seam are provided with an anticorrosive and/ or high temperature resisting layer 3. The welded type steel pipe fitting provided by the utility model has the advantages of lower cost, easy manufacture and convenient use.
Description
Technical field
The utility model relates to fluids such as being used to carry coal gas, rock gas or oil, particularly because the welding type steel pipe of the above-mentioned fluid of underground conveying.
Background technique
Because fluids such as coal gas, rock gas or oil are inflammable articles, and have corrosivity, strict demand is arranged for the pipeline of carrying this class fluid.Carry the pipeline of this class fluid to adopt simple steel pipe or iron pipe usually,, cause the waste of great amount of manpower and material resources because pipeline need be manually made regular check on and be changed in the not corrosion of the conveyance fluid of anti-institute of this material.
Consider underground length apart from the conveyance fluid process, pipeline can be subjected to the influence of the various factorss such as erosion of earthquake and soil, so when laying pipeline, the Placement between each pipe fitting becomes subject matter.
Existing Placement of laying subterranean pipe line mainly contains three kinds: flange plate connection, bayonet joint and welding.Flange plate connects uses bolton, with rubber parts sealing, and bolt is also loosening easily after fastening between two flange plate, particularly be subjected under the external force effect such as earthquake easier to be loosening, rubber parts is underground also perishable in burying underground for a long time, and bolt looseness and rubber parts are rotten all can to cause escape of liquid; Bayonet joint also causes birdsmouth to break away from the earthquake process easily, and then causes escape of liquid.So the pipeline of the above-mentioned fluid of conveying of provided underground only is suitable for welding.
This shows, owing to carry the pipeline of above-mentioned fluid, should guarantee that at first the parts of pipeline have decay resistance, secondly is that relatively low cost be arranged, and can field welding between the pipe fitting.Though Bai Gangguan 2 has decay resistance, simultaneously also can field welding,, price is very high.
In order to address the above problem, Chinese patent 200520093703.X " welding type plastic-coated steel " is a kind of scheme.This patent adopts is responsible for part, and its end is white steel pipe, and white steel pipe takes interference type to cooperate with being responsible for part, and then white steel pipe criteria of right and wrong specification does not cost an arm and a leg, and is exactly the manufacturing process complexity, and state-run cooperation also causes and is intended to complex process.
Summary of the invention
The steel pipe fitting that provides a kind of cost lower, easy to manufacture, easy to use is provided the purpose of this utility model.
The utility model provides a kind of welding steel pipe fitting, it is characterized in that: comprise person in charge's part 1 and white steel pipe 2, white steel pipe 2 is welded on the end of being responsible for part 1, has anticorrosion and/or high-temperature-resistant layer 3 on the internal surface of person in charge's part 1 and weld seam or the inner and outer surface.
The welding steel pipe fitting that the utility model provides, its white steel pipe 2 can have ground wire, to eliminate the static in the pipeline.
The welding steel pipe fitting that the utility model provides, the length of its white steel pipe 2 can be 10～25cm, does not damage with short white steel pipe 2 assurance Weldable Steel pipe fitting things and is responsible for part 1.
The welding steel pipe fitting that the utility model provides, its advantage is: cost is lower, easy to manufacture, easy to use.
